Ranunculaceae
Ranunculaceae (, buttercup or crowfoot family; Latin "little frog", from "frog") is a family (biology), family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are ''Ranunculus'' (600 species), ''Delphinium'' (365), ''Thalictrum'' (330), ''Clematis'' (380), and ''Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as ''Clematis'') or shrubs (e.g. ''Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in Cyme (botany), cymes, panicles, or spike (botany), spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera ''Aconitum'' and ''Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may ...

Oskar Eberhard Ulbrich
Oskar Eberhard Ulbrich (17 September 1879 – 4 November 1952) was a German botanist and mycologist. Ulbrich was born in Berlin. He studied natural sciences at the University of Berlin, where his instructors included Adolf Engler (1844–1930) and Simon Schwendener (1829–1919). In 1926 he became a curator and professor at the Botanical Museum in Berlin, where in 1938 he was appointed director of the ''Hauptpilzstelle''. Known for his intrafamilial investigations of the botanical families Amaranthaceae, Chenopodiaceae and Caryophyllaceae, in 1934 he subdivided Chenopodiaceae into eight subfamilies; Salicornioideae, Polycnemoideae, Chenopodioideae, Salsoloideae, et al. In 1911 he introduced usage of a color scheme to indicate geographical regions on herbarium specimens and fascicles. The plant genus '' Ulbrichia'' from the family Malvaceae was named after him by Ignatz Urban (1848–1931). Selected publications * ''Die höheren Pilze: Basidiomycetes'', third edition 1928 (wit ...

Hugh Algernon Weddell
Hugh Algernon Weddell (22 June 1819 – 22 July 1877) was a physician and botanist, specialising in South American flora. Weddell was born at Birches House, Painswick near Gloucester, England, but was raised in France and educated at the Lycée Henri IV, where he received a medical degree in 1841. He had also studied botany and became a respected member of the French botanical fraternity. While studying, he accompanied Adrien-Henri de Jussieu (1797-1853) on numerous botanizing expeditions and he became a collaborator with Ernest Cosson (1819-1889) and Jacques Germain de Saint-Pierre (1815-1882) in the preparation of Flore des environs de Paris (1845). In 1843, he was invited to join the expedition of François Louis de la Porte, comte de Castelnau to South America, and he explored and collected botanical specimens on that continent for five years. In May 1845, Weddell left the expedition which was then in Paraguay, and proceeded on a solitary journey which would take ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Peru
Peru, officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the south and west by the Pacific Ocean. Peru is a Megadiverse countries, megadiverse country, with habitats ranging from the arid plains of the Pacific coastal region in the west, to the peaks of the Andes mountains extending from the north to the southeast of the country, to the tropical Amazon basin rainforest in the east with the Amazon River.

Flora Of Peru
Peru has some of the greatest biodiversity in the world. It belongs to the select group of mega diverse countries because of the presence of the Andes, Amazon rainforest, and the Pacific Ocean. It has the fourth-most tropical forests of any country and the ninth-most forest area. The country is ranked among the five countries with the greatest biodiversity in the world according to various studies. Natural protected areas The 1993 Constitution of Peru recognized the natural resources and ecosystems of Peru as part of its heritage. In 1999, the National System of Natural Areas Protected by the State () was established by the Peruvian government. SINANPE consists of natural areas under national administration, managed and overseen by the National Service of Natural Protected Areas by the State (SERNANP). They also created a map of protection and preservation of historical–cultural heritage and nature. Peru has 76 natural protected areas (more of 15% of the country surface ar ...
